Abstract
A suggested form for the inhomogeneity found in certain thin films is a bilayer structure with a boundary layer of different refractive index from that of the main film. This boundary layer lies between the main film and the substrate. A simple formula is deduced to allow calculation of the index of this layer. For zinc sulphide the calculated results agree well with the possibility of the boundary layer being zinc oxide.Keywords
